Previous work utilizing machine learning techniques in QMB systems was
heavily focused on the use of restricted Boltzmann machines (RBMs) as
generative models of quantum
states.[1]}, [2]}, [3]} These are energy-based
models with an energy cost function given by
\(E(v,h) = -\sum _i{a_iv_i} - \sum _j{b_jh_j} -\sum _{i,j}{v_iW_{ij}h_j}.\)
